Fix enum variant suggestion consuming trailing parenthesis

- Closes rust-lang/rust#150459

Previously the logic incorrectly assumed the variant itself was the function being called when the parent node was a function all. This change adds a check to ensure the replacement span is only expanded if the path expression is actually the callee of the parent expression.
